Quantas also has really clever salad dressing containers that you squeeze while the top is pointing down toward your salad. A pointy bump in the middle opens up and the dressing goes where it's supposed to. Wonder why nobody else (AFAIK) has picked up on that idea? Maybe the upside-down part only works south of the equator? (I know QF flies north of there too, I just happen never to have had salad with them north of the line.)
